An interesting and revealing statistic shows that Spanish teams have the upper hand on English sides when they go head to head in the Champions League knockout stages by quite some margin. 

The stat reveals that La Liga clubs have eliminated Premier League teams 14 out of the last 18 times they have faced each other in the Champions League knockout stages.

This comes after Sevilla - who are fifth in La Liga - defeated Manchester United - who sit second in the Premier League - 2-1 at Old Trafford in Tuesday's last 16 game. 

Two goals in four minutes from Sevilla substitute Wissam Ben Yedder was enough to knock Manchester United out of the Champions League on a famous night for the Spanish side at Old Trafford.

This was another sign that there are many that underestimate the quality that La Liga possesses, as in truth, a fifth-placed Sevilla side played second-placed United off the park at Old Trafford. 

Spanish dominance in European competitions since the turn of the millennium is evident as La Liga clubs have amassed a total of 16 European titles since 2000, whereas English sides have won six in the same period.

The Spanish clubs have a chance to improve the stat as Barcelona prepare to host Chelsea at the Camp Nou when they come up against the English outfit on Wednesday.

Barcelona go into the game with a slight advantage after Lionel Messi left it late to get an away goal in the 1-1 draw at Stamford Bridge in the first leg.
